1. Cutting structure:
Using new formulas and new technologies, the durability of high-quality carbide blades has been improved. The steel teeth adopt high-quality tungsten carbide surfacing welding on the tooth surface to improve the wear resistance of the teeth by a small amount.
2. Gauge structure:
Multi-gauge protection, a gauge dresser at the rear, gauge inserts on the cone measuring surface, tungsten carbide inserts and surfacing on the tip of the palm, which increase gauge retention and bearing life.
3. Bearing structure:
High-precision bearing with two thrust surfaces. The ball locks the cone. The hard surface hears the bearing surface. The tapered bearing is inlaid with anti-friction alloy and then plated with silver. Improve the wear resistance and seizure resistance of the bearing, suitable for high speed.
4. Sealing and lubrication:
The advanced metal sealing package consists of two metal seats and two elastic energizers. The compression energizer keeps the two sealing surfaces of the metal ring in good contact through elastic force to achieve bearing sealing. In drilling, the metal seal is relatively dynamic, while the energizer is static. This will improve the reliability and durability of the bearing seal. Pressure compensation system and advanced grease can greatly improve lubrication reliability.

Tri-cone bit is a decelerating bit. It is based on the fact that the speed of the cone is less than the speed of the bit. It is suitable for sidetracking of old wells and deepening of small boreholes under high speed and high drilling pressure.
